Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Gold Recovery from a Gold Tailing by Floatation and Thiourea Leaching [PDF]

Proceedings of the 2nd Annual International Conference on Advanced Material Engineering (AME 2016), 2016
With the feature of high pyrite, high gold, fine gold dissemination in a gold tailing, experimental studies of floatation and thiourea leaching were carried out on a gold ore. The results showed that single floatation or thiourea leaching process was not suitable for this tailing.
